I want to verify the data in some Postgres dumps.
I’ve created a script that imports the dump into a fresh Postgres DB, and verifies the data.

This runs as a cronjob in Kubernetes.

The Cronjob contains two containers. The default container, running the script, and a postgresql container that is the database.

jobTemplate:
    spec:
      template:
        spec:
          containers:
            - name: verifier
              image: "verifier:v1.0.2"
              env:
              # ...
            - name: postgres
              image: postgres:16.1
              env:
                - name: POSTGRES_PASSWORD
                  value: test

This executes fine, but when the verifier script is done it is killed. While the postgresql container keeps running.

The pod remains in state Not Ready

verifier-28577575-zq24s 1/2 NotReady 0 57m

I’ve tried adding activeDeadlineSeconds: 720, but it does not seem to trigger.

Is there a way to take down the remaining containers when the default container has completed execution?
